What physical properties of an element NEVER change when it becomes part of a compound?
The atomic number and mass number of an element never change when it becomes part of a compound. These values are unique to each element and are constant regardless of its chemical state.
Is chlorine a non - metallic compound?
Chlorine is a nonmetal but its is an element, not a compound.
Did cl change oxidation number tue or false?
True. A change in oxidation number occurs when there is a transfer of electrons from one atom to another, leading to a change in the oxidation state of an element in a chemical compound.
